1 farad capacitor

To test a super capacitor you need to remove the faulty one and discharge the power running through them. Next, start a capacitor tester and watch the pointer on its meter.

A Polarized capacitor means that the capacitor is polarity sensitive. if you were to connect the capacitor incorrectly the capacitor would blow up. A capacitor that is marked as being polarity sensitive will have the negative lead labeled usually with a white strip. These capacitors can only be used in conjunction with a dc source. Always consult a professional when installing electrical equipment.

We need 200 tens to make 2000. 2000/10 = 200 So, there are 200 tens in 2000.

No, but certain types of AC single phase motors need a "startup capacitor" to make sure they start turning in the right direction when power is applied.

You need a multimeter that is capable of testing micro Farads (uF). The capacitor is normally stamped with this rating. Should get a reading within +/- 5% of the rated value. Some Caps. are polarity sensitive so make sure your +/- leads from your meter are correct

A capacitor is like a 0.001 ohm resistor when the capacitive reactance is 0.001 ohms. Capacitive reactance, in ohms, is defined as -1 divided by 2 pi f C, where f is frequency in hertz, C is capacitance in farads, and the -1 means that current leads voltage. Plugging in 60 Hz, and solving for C, you get 2.65 farads. That is a very large capacitor. At 6000 Hz, you get 26.5 millifards, which is still very large. At 6 MHz, you get 26.5 microfards, but at 6 MHz, you need to consider parasitic inductance.

I assume that you are asking how to calculate the 'value' of a capacitor? Well, it depends what it is used for. If, for example, it is used to improve the power factor of a load, then it is first necessary to determine what the load's existing reactive power is; then, you need to know what reactive power is necessary with the power factor at its desired value; finally you need to difference between the actual and the desired values of reactive power -and this will be the necessary value for the capacitor. Power factor correction capacitors are rated in reactive volt amperes, not farads.

In general, no. You need to use the correct capacitor as designed for the circuit.

You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.

You don't. A polarized capacitor is inherently polarized due to how it is made. If you need a non polarized capacitor, buy a non polarized capacitor.

The time it takes to fully charge a capacitor depends on the capacitance and resistance of the circuit; the voltage is irrelevant. The equation you need is:t = 5RCwhere: t = time in seconds, R= resistance in ohms, and C =capacitance in farads.So you should now be able to calculate the time for yourself, but remember to convert the resistance into ohms and the capacitance into farads before you insert the figures into the equation.

A car battery does not need a capacitor as it's regulating capacity (when in good condition) is well above any capacitor you can fit into your car.
